MEDICATED NEST-EGG- Specification of Letters Patent.

Patented April 10, 1906.

Application filed August 2, 1905. Serial No. 272,838.

To all whom, it may concern.-

Be it known that I, GEORGE HERBERT JONES, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Medicated Nest-Egg, of which the following is a full, clear, and ex act description.

This invention relates to medicated nesteggs such as poultrymen place in the nests used by their fowls in. order to destroy or drive away vermin. It is desirable that the eggs used for this purpose should not give off the fumes too rapidly, because under these circumstances when they are placed under setting-hens they endanger the lives of the embryo chicks.

The purpose of this invention is to produce an egg of the class described of very simple and desirable construction and in which the medicated compound may be placed with facility, and, further, to provide means whereby the exudation from the egg will take place slowly and substantially uniformly.

The invention consists in the construction and combination of parts of the materials, to be described more fully hereinafter, and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of an egg constructed according to my invention. Fig. 2 is a longitudinal section of the same, taken on the line 2 2 of Fig. 1 and Fig. 3 is a transverse section on the line 3 3 of Fig. 2.

Referring more particularly to the parts, 1 represents the body of the egg, which is of the form and size of a natural egg. This body is provided with a longitudinal bore or pocket 2, which extends inwardly from the tip of the e g and is central with respect to the longitudinal axis of the egg. At the tip of the egg a counterbore and a recess 3 is formed.

Within the pocket 2 I place an absorbent plug or core i, which is retained in place by a cap 5. This cap 5, as indicated in Fig. 1, is of circular form and provided with perforations 6. Its edge rests in the counterbore 3, as indicated in Fig. 3, and the cap is of convex form, so as to continue the outline of the eggtip, as will be readily understood. Upon the inner face of this cap 5 I attach a core-holder 7, which is preferably attached centrally to the cap by means of a hollow rivet or eyelet 8. This core-holder consists of a flat strip, which is bent near its point of attachment to the cap, so as to conform to the curvature of the inner face of the cap, and beyond this point the ends of the strip are bent laterally, so as to present parallel fingers 9, between Which the core 4'is adapted to be received, as indicated most clearly in Fig. 8. The fingers 9 are of sufficient width to enable the plug to be jammed tightly within the body 1 of the egg, as indicated in Fig. 2. When the plug or core is placed within the egg in this way, the cap 5 seats itself at the end of the egg, and the egg presents substantially the appearance of an ordinary egg. The core or plug 4 is preferably formed of a light woody absorbent material. For this purpose I prefer to employ the bark of the giant redwood tree of California, which is a species of cedar and is found in this locality. The body 1 of the egg is preferably formed of the wood of the tree referred to, the heart of the wood being selected in this instance in preference to the bark.

In preparing the egg for use I pour into the pocket 2 a liquid insecticide containing substances such as camphor, carbolic acid, oil of sassafras, which substances are deleterious to insect life. The core 4 is allowed to absorb this liquid, and a portion of the liquid is also absorbed by the body of the egg.

The outer surface of the body 1 is coated with white paint or a similar substance, which gives it substantially the color and appearance of a natural egg and at the same time operates to prevent evaporation of the insecticide through the pores of the outer surface of the body of the egg. In this way the exudation of the insecticide from the egg is rendered less vigorous and becomes more uniform, being prolonged for a great period.

I have discovered that the material which I use for the core of the egg is especially valuable, because it absorbs a large quantity of the liquid and because evaporation from it takes place at a very slow rate. On this account there is little danger of injury to the eggs which may be under the hen at the same time as the medicated egg, it being understood that while the exudations are sufficient to drive off the vermin they are not suflicient to endanger the stronger vitality of the growing chicks. The heat from the body of the hen tends to drive the exudations inwardly ICC toward the pocket 2, and the fumes thus liberated pass through the perforations 6 into the space under the hen.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A medicated nest-egg comprising a woody fiber, the pores whereof nated with an insecticide.

2. A medicated nest-egg having a body with a pocket formed therein and a core of woody fiber within said pocket, the pores of i said core being impregnated with an insecti I cide.

3. A medicated nest-egg having a body 1 with a pocket formed therein, a core of wood fiber within said pocket, the pores of said. core being impregnated with an insecticide, and means for retaining the said core within said pocket. i

are impreg- 4. A medicated nest-egg having a body' with a pocket formed therein, a core of woodbark held in said pocket, the pores of said core being impregnated with a liquid insecticide.

5. A medicated nest-egg having a body with a pocket formed therein, a core of absorbent material received Within said pocket, said core having its pores impregnated with an insecticide, a cap closing said pocket and having a core-holder attached to the inner face thereof and engaging said core to retain the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE HERBERT JONES.
